Plasma levels of sirtuin 1 and sirtuin 2 in ascending aortic aneurysm patients - a comparative study.
Article in Cardiology journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundStudies of animal and human aortic tissue samples showed that sirtuins may protect against aortic aneurysm (AA). However, to date, no studies have assessed plasma or serum sirtuin levels in humans. Therefore, the aim of this study was to evaluate associations between plasma sirtuin 1 (SIRT1) and sirtuin 2 (SIRT2) levels and the presence of ascending AA.
methodsPlasma SIRT1 and SIRT2 levels were assessed in patients with and without ascending AA using an enzyme-linked immunosorbent assay.
resultsThe study included 32 patients with ascending AA (median age: 67 years) and 37 controls without AA (median age: 68 years). Plasma SIRT1 and SIRT2 levels did not differ between groups (p > 0.05). However, slightly higher sirtuin levels were observed in patients with ascending AA than in controls, particularly for SIRT1 in the subgroups of patients without coronary artery disease, atrial fibrillation, and chronic obstructive pulmonary disease (COPD). Among patients with ascending AA, higher SIRT2 levels were noted for those without COPD vs. those with COPD (p = 0.04).
conclusionsThe study showed no significant differences in SIRT1 and SIRT2 levels between patients with and without ascending AA. However, there was a trend towards higher SIRT1 levels in patients with AA, especially in those without comorbidities.
